  - haproxy: does not ensure that the scheme and path portions of a URI have the expected characters
    (CVE-2021-39240)

  - haproxy: an HTTP method name may contain a space followed by the name of a protected resource
    (CVE-2021-39241)

  - haproxy: it can lead to a situation with an attacker-controlled HTTP Host header because a mismatch
    between Host and authority is mishandled (CVE-2021-39242)

  - haproxy: request smuggling attack or response splitting via duplicate content-length header
    (CVE-2021-40346)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
